DEP-2: Update on the information flow
Note to re-ask ourselves the question whether we can get a consensus on
having to modify all Debian services to directly send the mail to the
DPMH and only there (i.e. no longer to the Maintainer field).
Clarify that if the Maintainer field is replaced, its former value is
moved to Uploaders.

Consistent spelling of our terms:
- line based -> line-based
- standalone -> stand-alone
- single line -> single-line
Consistent links when talking about paragraphs (always include "paragraph"
as part of the link name)
